摘要：Introduction: Bicycle helmet use is recognized as an effective way to prevent head injuriesin cyclists. A number of countries have introduced legislation to make helmetsmandatory, but many object to this type of measure for fear that it could discouragepeople, particularly teenagers, from cycling. In 2011, the City of Sherbrooke adopted abylaw requiring minors to wear a bicycle helmet. The objective of this study was toassess the impact of this bylaw on cycling and bicycle helmet use.Methods: The impact of the bylaw was measured by comparing the evolution of bicyclehelmet use among youth aged 12 to 17 years in the Sherbrooke area (n = 248) and inthree control regions (n = 767), through the use of logistic regression analyses.Results: Cycling rates remained stable in the Sherbrooke area (going from 49.9% to53.8%) but decreased in the control regions (going from 59.1% to 46.3%). This differencein evolution shows that cycling rates increased in the Sherbrooke area after theadoption of the bylaw, compared to the control regions (odds ratio [OR] of the interactionterm: 2.32; 95% confidence interval [CI]: 1.01–5.35). With respect to helmet use, anon–statistically significant upward trend was observed in the Sherbrooke area (goingfrom 43.5% to 60.6%). This figure remained stable in the control regions (going from41.5% to 41.9%). No significant difference was observed in the evolution of helmet usebetween the two groups (OR of the interaction term of 2.70; 95% CI: 0.67–10.83).Conclusion: After the bylaw was adopted, bicycle use among youth aged 12 to 17 yearsin the Sherbrooke area remained stable and helmet used increased, though notsignificantly.
